Koh Bon West Ridge

Koh Bon's western ridge is Thailand's most reliable manta station. The limestone spur steps down from the island to a nose at around 18-25 m where cleaning stations operate, and reef mantas arrive on their own schedule to bank in slow circles overhead, sometimes one, sometimes a squadron that stays the whole dive. Etiquette is drilled: hold the reef side, stay low, let the animals run the geometry. Manta-less days still pay in yellow soft coral on the ridge's north face, octopus in the rubble, and napoleon wrasse cruising the steps. Liveaboards revisit until the mantas oblige.

바로 그 순간: Reef mantas at cleaning stations, a diveable ridge line in all currents, repeat-visit rhythm

지형: Limestone ridge stepping down to a deep point

조류: The ridge nose catches flow from both sides; mantas prefer it that way.

위험 요소: Current at the nose and depth creep following mantas off the ridge.

보존: Cleaning stations fail when divers crowd them; the low-and-still protocol is enforced by every good crew.
